Feature Not Available
The units shall be supplied with a European ROHS Directive 2002/95/EC compatible microprocessor controller
connected to an 8 x 22 back-lit LCD keypad display. LEDs shall not be acceptable. The microprocessor controller offers
powerful analogue and digital control to meet a wide range of monitoring and control features including a real time clock
and Industry standard communication port and network connections.
All the boards feature a 16 bit microprocessor, and consequently the calculation power and operation processing speed
have been significantly increased. Also featured are a visual alarm and the facility to adjust and display control settings
by local operator for information and control.
Display/Keypad
The display keypad features a simple array of keys to navigate through the in-built menus.
With an 8 x 22 character (132 x 64 pixel) screen size, back lit in white for improved contrast, the larger screen shall
provide for user friendly viewing and easy status recognition by displaying a combination of text and icons.
The default screen shall show the unit status without the need for interrogation and an easy to navigate menu structure
for further interrogation and adjustment shall be provided.
Alarm Log
The controller shall log and allow viewing of not less than the last 200 conditions recorded in descending chronological
order through the keypad display.
The standard display keypad shall visually display operating alarms, however, as an optional extra, a display keypad
with audible alarms is available.
BMS Interface Cards
BMS Interface Card controlled units shall be interfaced with most BMS, factory fitted, please contact Airedale.
A wide range of protocols shall be accommodated through the use of interface devices. Available as a standard option
are: ModBus/Jbus, and Carel. For interfaces such as SNMP, LonWorks, Metasys and BACnet, please contact Airedale.
Also available shall be Airedale’s own supervisory plug-in BMS card pCOWEB, based on Ethernet TCP/IP secure
technology with SNMP features. It shall require no proprietary cabling or monitoring software and be supplied pre-
programmed with an IP address for ease of set up. Cables to the BMS to be supplied by others.
